This step is only required if you have a backlit serial LCD module and the power connector/lead was supplied with your LCD. |
The supplied connector needs to be soldered in the pads labeled "GROUND", "+5V(LCD)" and "+5V(LED)" on the back side of the LCD as shown in the following images.
Make sure the connector is soldered in place facing in the same direction as in the image below. |

For the CrystalControl to work correctly, the baud rate on the LCD and the rate selected in the software must correspond.
For example, if the LCD is set to 9600 baud, CrystalControl must also be set to use 9600 for that module.
Generally 19200 baud is the best to use as it'll give the fastest LCD update speeds, and reduce flicker.
Sometime a lower baud rate may be preferred. A good example of when the baud rate may need to be reduced is when using the LCD over a very long serial cable.
|
The images below show the dip-switch that sets the baud rate on the LCD, and the table on the back of the LCD showing which switch positions correspond to a particular baud rate. The dip-switch in this case is set to 19200 baud. |

If supplied, use the serial cable supplied with the LCD to connect the LCD to a serial port on the back of your PC.
If you did not purchase the serial cable with your LCD, you will need to acquire a 9pin female to 9pin female "straight through" serial lead (not "null modem" type). |
If you have the backlit LCD module and purchased the backlight power supply lead with the LCD, connect it to the LCD and the "molex" connector to a power supply cable in your PC. |
